The two Republican commissioners, Robert McDowell and Ajit Pai, have cast electronic votes to approve the agreements, joining FCC Chairman Julius Genachowski, two unidentified agency officials told Bloomberg News. The FCC's two Democrats, Jessica Rosenworcel and Mignon Clyburn, haven't voted yet, according to the report.

Genachowski said last week he would move to approve the agreements after the Justice Department reached a settlement agreement with Verizon Wireless and the cable companies.

Verizon Wireless is purchasing $3.9 billion in spectrum from Bright House Networks, Comcast, Cox and Time Warner Cable. Verizon Wireless and the cable companies also have entered into co-marketing agreements and a joint technology venture.

Justice Department officials said the companies have made concessions that will protect competition between Verizon Wireless and the cable operators.
